Just a few months removed from the release of the iPhone 5, rumors are already beginning to swirl about the latest and greatest Apple phone.

Citing a letter written by Topeka Capital Markets analyst Brian White, tech website bgr.com reports the new iPhone 5s will launch in either May or June and come in more colors and screen size option than previous versions.

"White believes the next iPhone will be available in five different colors: pink, yellow, blue, white & silver and black & slate," bgr.com's Zach Epstein wrote . "He also believes there will be two different screen sizes available on the device, marking the first time Apple has released one phone with multiple display size options."
